Witryna26 sty 2015 · This metric typically takes values between 0 and 1, where values near 1 indicate that a SNP has been imputed with high certainty. The info metric is often used to remove poorly imputed SNPs from the association testing results. Different thresholds were recommended for different MAF categories.
